A Fusion saddle company close contact saddle, in black.
It looks like a monoflap but it is not.
It has long girth straps so you would need a dressage type girth.
In my opinion it is a medium width measuring approx. 8 inches from d-ring to d-ring, and has a 17.5 inch seat.
Showing normal signs of saddle wear as it is used.
